摘要：
Described embodiments include a method that includes constructing a computerized electroanatomical model of a portion of a heart, the model including a mesh, which approximates the portion of the heart, and a plurality of points, at different respective locations on the mesh, having respective associated local activation times (LATs) that were ascertained from electrocardiographic signals acquired from the portion. The method further includes constructing a graph that interconnects the points and, based on the respective locations and LATs of the points, identifying, from a plurality of pathways, through the graph, from a first one of the points having a lowest one of the LATs to a second one of the points having a highest one of the LATs, both a shortest pathway and a longest pathway. The method further includes displaying the mesh, with the identified shortest pathway and longest pathway superimposed over the mesh. Other embodiments are also described.
